To (1/6 'Ifi/LO'HZ- it may (107166771 Be it known that we, JUSEPII F. JlROUSEK and Ninnon '1. Piarniiiin. citizens of the United States of America, residing at Shelby, in the county of ltichland and State of Ohio, have invented certain new and use.- tul linprovements in interleaving Devices, of which the 'liollowing is a specitirationv This invention relates to an interleaving device that can be used and readily attached or removed from a. cylinder printing or lithographing press (or it can be arranged to be used with another machine) and is adapted to deliver a single sheet ot' paper from a pile upon a printed sheet, as it is delivered from the press or other device, thereby interleaving the sheets delivered from the interleaving device with the sheets delivered from the press or other machine.

The objects of the invention are to dispense with an extra operator. who in the present practice required to interleave the sheets by hand manipulation, by PlOt'ltllllg means to interleave the sheets automatically; to increase the production oi the press by increasing the speed of the press, which is accomplished and made possible because of the means provided for interleaving the sheets automatically instead ot by hand mani 'iulation; to provide means to deliver the sheets for inter-having purposes uniforinly and accurately, thereby preventing any tendency ot the sheets to move on the surface of the others as they are being delivered; tt. economize in floor space byaniak ing unnecessary the. use of tables and other apparatus which are now used to" support the sheets for interleaving purposes by hand manipulation; to provide automatic means for inserting either the original or duplicate sheet of a series ot' sheets tor inanitolding purposes, while the remaining sheet. is being printed, thereby doing away with the bindery operation known as collating;"to provide means of stoppin the operation of in" the operation oi the-'pr and ineit'nsto automatically throw the interleaving machine into operation: to provide means tor the rapid ittltltflllHLlll or removal (it my device troiu the press: and n ans to relieve the pressmau and teeder oi: the necessity of giving any attcutiou' to the interleaving process and ot the interl'erence with either in the performance of their duties by the interleaving operator.

derived from different sources with each other; said interleaving being accomplished in. a more perfect, rapid and uniform manner than has heretofore. been accomplished by hand manipulation, thereby saving time and labor, and producing a. better quality of Work.

This inventi n further consists of: other novel features. details of construction and combination of parts which will hereinafter be, more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claims.

Fig. 20 is a plan view of the bottom of the suction foot shown in Fig. 19. Fig. 21 is a side elevation of the trip mechanism which is secured to the stop bar 1. The operation of the trip mechanism being shown in dotted lines. Fig. is an end view of Fig. 21. Fig. 23 shows the method of communicating rotary motion to the reels by a pulley and cable and an outline of the whole device assembled and mounted upon the tracks. Fig. 24 is a perspective view of thedevice, showing the arrangement and location of the parts when assembled and ready to be mounted upon the tracks.

The device as shown is preferably constructed to operate in connection with a printing press which delivers the printed side of a sheet of paper upward and in its operation requires a track on each side tending to a point slightly beyond the delivery table or platform at the front of the press, oneform of which is shown in Fig. 14.

In the escription of the device, one side only will be described as it will be understood that both the right side and left side are exact duplicates of each other (see Fig. l) 'e-xcept that on the right side of the device an operating mechanism-is attached for operating a pump and regulating the suction thereof; also means for regulating and operating the suction foot. lVhat is herein designated the right-hand side of the machine is to the right side of person, looking at the machine as shown in Fig. 1 of the drawings.

In the accompanying drawings, reference numerals 0-0 represent the tracks upon which are rigidly secured atthe forward ends, vertical stop bars 1-4; and at their rearward ends, vertical stop bars l-,-1.

Upon the tracks a carriage 2 is mounted which is supported by flange pulleys 33, the flanges of which depend on each side of the track to prevent undue lateral movement. It will be noted that the pulleys are secured to the forward end of the frame 4 and support its front end. The rear end being suppported in amanuer which will be described hereinafter. It will, of course, be understood that means ciprocate the carriage and the mechanism mounted thereon, upon the tracks between the vertical. stops hereinbefore described. ()ne means being shown in Fig. 14 of the drawings.

in order to provide means for quickly attachiu or removing the device from the car are provided to reriage, an inverted U-shapcd lug 2 is atinched on each side of the bottom of the frame t. The U-shaped lugs engage the tie-' rod 2 which connects both sides of the carriage On this tie-rod, collars A-A are secured and held in place by setscrews to pre vent movement of the device in a lateral direction.

In order to prevent the device from vibrating or moving in a vertical direction, a pin Z) is inserted in a suitable aperture formed in the U-shaped lug and it is adapt ed to contact slightly with the tie-rod 9 thereby preventing movement of the U-shaped lug and the mechanism carried thereby. (See Figs. 1, 4 and 14.)

The frame 4 is preferably constructed rectangular vibrating or upward 1 in form and of any required size noeeasv and is made of angle iron for the purpose of adding strength and rigidity thereto. The portions 5 of the frame t form supporting ledges for the means that carry the feed board (3. A frame 6 is supported by the ledges 5 of the frame through the medium of the trunnions 6 which are fastened t both frames 4: and (5 by the bolts 8. tion is called to the fact tliatftlie feed board is removable and any number of boards may be provided on which a pack of paper com- Fprising a pack of sheets may be placed in the proper position and when one pack is exhausted, another pack can be placed in osition without unduly delaying the operation of the press and the device in performing the interleaving operation. The rear end of this frame 4; is preferably supported by yokes '7 which extend down to the track at which point the yokes are supported by the flange rollers 9 which travel on the tracks and support the rear end of the carriage upon which the device is mounted. These yok es are connected by an angle bar 10 which retains the yoke onboth sides in their proper position and gives rigidity to the yoks when subjected to strain in the op; eration of the device. Lateral movement of the rear end of the carriage is prevented by the flanges 9 of the rollers which rotateand travel adjacent to the inside of each track. When the de vice is made to travel rearwardly on the tracks 0-0 to its rearward terminus and the different parts are engaged by the vertical stop bar 1, there is a tendency for the carriage to tip upward at its rear which is caused by ,the resistance of the vertical stop bar 1 to the movement of the carria In order to overcome the tendency to tip and hold the carriage on a plane with the tracks at the rear end, two or more vertical bars 10 are attached to the outside of the tracks and to the tops of these vertical bars, a horizontal bar 10 is secured which is placed parallel with the top of the track and the proper distance above it to permit the rear flange pulleys J to travel between the horizontal bar and its respective track. (See Figs. 1-1:, 16 and Q3.) The horizontal bar is made of su'liicient length to maintain the flange pulley 9 between the track 0 and itself during? that part of the travel of the carriage (and the mechanism mounted thereon) that part of the mechanism being resisted by the vertical stop' bar it. i w/ a At a pro-determined point on thotinner of each yoke 7, an arm ll lspivotultv connected with its free end extending forward and rigidly connected to the 1' air end of a box 17 hereinafter described. The object of this arm, (one of which. is located on each side of the device) is to pc mit the raising and lowering of the operating mechanism of the device, simultaneously and its l moval of the sheets 0 Atteir l l l l l l i li l dev ice.

to the varying height of sheets caused by the rehy the device for interproper adjusti'ncnt the pack of paper leaving.

On the frontend of each side of the frame 4, a framework 12' is provided each consisting of four vertical bars l2) spaced apart and arranged to permit of the insertion ictween them of a box or boxes (.arrying sliding mechanism. lhc upper ends of these bars .13 are spaced apart and attached together by means of a bar it which forms .a top for the framework and the lower ends of the bars 13 are rigidly secured to the frame at and the block t. The framework on each side, just described is connected together by an angle iron bar 1.? which sccurely attached to the ars l-l forming the top of the frameworl-z 12. The angle bar 15 is also i. d to support portions f the opi-zrating mechanism of the device and for holding the whole of the mechanism at its highest point in order to aiii'ord space for replenishing the pack of paper sheets on the feed board. Vertical. guide bars it) are socured on the inside of the frai-ncwi'irk on each side of the macl inc, one endbcing attached to the horizontal bar l5and the other end being attached to a block l which is secured to the frame l. v

A supporting box 17 which is provided with a longitudinal groove 1Tv and a vertical slot 17- is fitted within the vertical bars of the framework 12 in such a manner as to permit of vertical sliding movement. in the longitudinal. groove 17, formed in the box l7 a horizontal. sliding bar to is inserted which projects beyond each end of the box. [uljaccnt to the forward end of the sliding bar lh a stud l9 is secured extending outwardly in ahorizontal direction, which is adapted to engage the vertical stop bar i. when the device reaches a prc-dctermined point in its :lorward travel. in order to keep the slidingbar 18 within its proper place in the longitudinal groove. two bars is and iii are secured to the box 17 with their inner edges extending over the top of the sliding bar 1%.

Adpicent to the rear ot the cam i a pin is secured which engages a similar pm 2t secured to the pivoted pawl 25.

is SQil ll'Otl and bar 13. thereby On the inside of the front end of the sliding bar .18, an arm 26 is attached or made integral, with the slidingbar 18 which depends in a downward directionand in the lower end of which the supporting shaft 27 is secured, on which is carried the primary extension finger 28 which rests upon the pack of leaves and it also carries .the weight of the mechanism when the device is on its rearward travel and the secondary reel supports 29, which support the reel mechanism. The reel supports and extension finger are constructed in such a manner as to be readily adjustable either laterally or around the shaft 27. In the end of these supports and extension finger, rollers are journaled which contact with the delivery reels and impart movement to the sheet and obviate undue friction. To the top of the inner side of the box 17, two vertical bars 30 are attached, spaced apart and held together upon the upper portion by a horizontal bar 31'. The three bars in connection with the side of the box 17 form a guide-way in which the supporting reel bar 32 operates vertically when movement is imparted to it by the cam 22. Near the top of the supporting reel bar 32, a stud 32' is secured upon which a roller 33 is mounted and when riding on the cam 22 raises or lowers the reels and their mechanism.

In the lower end of the supporting reel 32, a bearing is provided to journal one end of the primary reel shaft 34. Attention is called to the fact that this shafbextends on each side beyond the framework 12 and on each end a sheave driving pulley 35 is mounted. On the shaft 34, a collar 36 is mounted adjacent to the primary reel sup porting bar 32' and at the side of this collar, a horizontal bar 37 is secured, the forward end of which is provided with a bearing to journal the secondary reel shaft 38. The primary reel 39 is adjustably mounted on the primary reel shaft 34 preferably adjacent to the center thereof. The secondary reel shaft 38 on one end is mounted in a bearing formed in the front of'the horizontal bar 37 and is held in place by the driven sheave pulley 40 placed at each end of the shaft 38 and contacting with the bar 37. A sheave pulley 40 is also mounted on the shaft 34 and alined with the pulley 40 on the shaft 38. Movement is thereby transmitted from the primary shaft 34 to the secondary reel shaft 38 by means of belts 40 or any other well known means of transmission. On the secondary reel shaft 38, reels 41 are adjustably mounted. It will be seen that the primary delivery reel 39 is designed to operate on the center of the sheet about to be delivered, and the secondary delivery reels .41 near the sides of the sheet, all of the reels being adjusta ble sidewise on the shafts to accommediat =v different.

providing a slot 42 in thebar 43, the secondary reel shaft 38 can be adjusted up or down to give the desired pressure of the secondary reels 41 on the secondary'reel supports 29, in order to insure the proper delivery of the sheet. In other words, the pressure between the supports and the delivery reels can be varied to suit the weight, kind or condition of the sheets of paper. At the rear of the primary reel shaft 34, a vertically movable rod 45 is secured which carries the standards 45, which in turn carry adjustable presser feet-46. The rod 45 also carries the sheet lifting mechanism consisting of the suction foot, the mechanism for operating it and other parts of the device. The rod 45 may be constructed of any desired form that shown in the drawings being round and braced by a truss 47 In the pillar 47 which is carried by the rod 45, astud 48 is secured and is adapted to engage a catch 49 which'is maintained to 9 swing on a pin secured to the front side of the horizontal bar 15, and when connected to the pin, supports the operating mechanism of thedevice when raised to its high est point, thereby giving access to the feed 10 board and the pack of sheets of paper car-. ried by the feed board.

On each end of the rod 45 a vertical sliding member 50 is secured and is formed channel shape to embrace a vertical guide bar 16. On the front and back of the vertical sliding member 50, horizontal projections 51-51 are provided, extending forward and backward. These projections are provided with suitable apertures through which the rods '52 are passed carrying springs 53, and adjusting nuts 54 surround the rods 52. Extending on each side of the vertical bar 16, a support 55 for the bolts 52 is provided which is attached to the box 17, and extends downward below the vertical sliding member 50.

Attention called to. the fact that the springs 53 are interposed between the horizontal projections 51 and the support 55, exerting a pressure upward against the horizontal projections and normally holding the rod 45 and the vertical sliding member 50 (when not restrained) in their upward positions. Adjacent to the vertical sliding member 50 on the rod 45, a cam roller 56 provided which eliminates part of the friction caused by the sliding movement of the cam 57 when actuated to force the rod 43 to its lower position. 35:

the locking; pawl engages porting the weight of: the operating niechtop of the Vertical anisin through the standards" and presser feet-uvhicli are then resting upon the pack of paper. [he pivoted locking yieldingly held against the vertical. sliding member. by the spring 59 which normally forces the, pivoted pawl .in contact with the vertical sliding member, preparatory to engaging the top of the vertical sliding; member when. forced downward to permit the lip 'of the locking pawl to engage therewith. At a point on the outer side of the pawl 25 and in a line to engage a pin 23 on the side of the cam 22, a pin 24; secured. d On the inner side of the box 17 and. on "the inner side of-the pivoted arm 11, brackets and (ll are attached. ..The brackets are provided with slots 62 in vhich rollers (32 are mount ed and spaced apart to form a slidcway through which the cam 57 operates. The front of the cain 57 is formed in. such a mannor that when the cam is pushed backward to the proper position the upper portion of the cam projects over the cam rollers 56 and when pushed forward, it forces the vertical sliding member 50 downward, compressing the springs 53 until the upper portion or sliding member 50 is engaged by and held down by the lip 58 of the pawl 2f I It Will be noted that the roller bearings (32 are so arranged in the slots formed in the braokets fiil and 61 that together they form a slideway which. retains the main cam 57 firmly in its proper position and atthe same time permits the com to slide freely and-Without friction in a horizontal, direc tion. At the rear end of the cam 51a stud (i3 is secured which extends outwardly and. 'n ahorizotital direction for euoughito perv initit to ons age the device has traveled in a rearward direction a pro-determined distance.

As the adjustment of the parts must be quite accurate with. reference to-theiroon. tact with the vertical stop bars, it-is deemed preferable to enlarge the. stud at the end point it comes in contact with the stop bar. =The enlarged part of the stud (33" acts asa head and contacts with the side of the rod 64:. The stud G3 is attached to the rod ti t which. extends forward along the outer side of-the 't'raiuoworl: 12 and is provided on its ltrce end with a roller 65 which adapted to (1:3 and form it eccentric at the engage the vertical stop bar 1 on its ton ward travel. The cam 57, stud 63, and rod 1 pawl 25 is the vertical stop barlovhen cl practically term a yoke. The opposite end of the stud is provided with a thread to engage the nut 373' which when tightened securely holds the cam 51'' and rod ill in closecontact with and between the ends oi? the sleeve (33. The rod t is supported on one end by passing it through a supporting bearing on \vhicli attached to the outer side of the box 17.

The presser feet 46 are so they can tical direction for any purpose desired.

arranged that The 'guides 67 are mounted on the bar t?) in close proximity to the presscr "feet 4.6 and extend in a forward direction under both of the reel shafts to keep each sheet of paper as it is drawn from the pack of paper sheets, traveling in its proper course. A loop forming mechanism for the sheet consists of a suction foot 68, loop regulator 69, hold by a bolt. 70, and the suction pump 100. On the rod 45 near its center, a bracket 71 is adjustably foot and its operating mechanism.

From the bracket 71 in front of the rod 45, an arm 72 is suspended and in the lower end of'said arm a pin 72 is inserted carrying a flanged roller '73 which supports one end of the suction foot cam 74. In the bracket- 71 an aperture is provided to receive a vertical guide rod ,75. The upper end of said rod is connected by an arm 76 to the suction toot tube 77. To the vertical guide bar under the .suction foot bracket arm 71. a pin 78 is attached carrying a cam roller 78.

It will be noted that the flanged roller 73 is stationary while the cam roller 78 is movable by the cam in a vertical direction. "When the suction footcam 74s is pushed'he tween said rollers, the cam raises the vertical gilidc bar 75 and elevates the suction tootflits, and when the cam. is Withdrawn vfrom between the rollers, the suction foot 68 is lowered. adjustably hold in place by lock nuts 77 which are pieced above and below the arm 76 by means of which the suction foot tube can be adjusted vertically.

' In the front end of the bracket 71, a
